Congress today demanded a ban on Sri Ram Sene after the right wing outfit's chief Pramod Muthalik was allegedly caught on camera accepting money to vandalise an art exhibition.

"If these facts are proved, then there should definitely be a ban of Sriram Sena. Moreover, there is a need for consideration about the role of even those organisations, which patronise it," party spokesperson Shakeel Ahmed told reporters at the All India Congress Committee briefing.

He said that the sting operation had exposed a "business of riots", which is a matter of concern for the country and society.

Lashing out at Karnataka Chief Minister BS Yediyurappa, AICC general secretary Digvijay Singh said the BJP leader does not have the courage to arrest Muthalik.

"Yediyurappa should take strict action. Muthalik should be immediately arrested. What other proof is required, when he has been caught on camera demanding cash. But the Chief Minister does not have the courage to take action against the Sene chief as he knows it is through these people his party creates communal divide to come to power," Singh said.

To a question whether RSS should be banned, Ahmed said it is for the government to decide. "More facts will come and all the organisations with whom the Sene is linked can be probed," he said.

He added "the country knows which are the organisations, which have promoted Sri Ram Sene. The same organisations are now trying to distance themselves from it after the sting operation."

Stressing that "there is a need to keep an eye on both Hindu as well Muslim fundamentalism," Singh said, "When I was Chief Minister, I had demanded a ban both on Bajrang Dal and Student Islamic Movement of India (SIMI)."

Referring to incidents like Samjhouta Express blast and Mecca Maszid blast, Singh said probe findings exposing the hands of Hindu fundamentalists behind them need to be seriously examined.

"Even in Nanded bomb blast, some confessed that they were trained by Bajrang Dal....All these things need to be looked into by state governments and the Government of India. There is a need for serious thinking and investigation on who gives them training," he said.

Last week, in his meeting with Home Minister P Chidambaram, Singh had raised the issue of activities of radical Hindu outfits in the wake of names of some alleged RSS activists surfacing in connection with the Ajmer blast.

He had also discussed the cases of terror violence in Indore and Ujjain as well as the issue of terror cases against Azamgarh youths and reiterated his demand for their speedy trial.

Asked about Batla House encounter, Singh said he is still "not convinced" about the encounter. "But I am not making an issue out of it," he added.
